Hypovolemic shock that results from an internal shifting of fluid from the intravascular space to the extravascular space is known as
 
  a. absolute hypovolemia.
  b. distributive hypovolemia.
  c. relative hypovolemia.
  d. compensatory hypovolemia.

Question 2

A patient's ICP is 34 mm Hg, and his cerebral perfusion pressure is 65 mm Hg. Which of the following is the most appropriate intervention?
 
  a. These are normal values, and no interventions are required.
  b. Administer mannitol 1 to 2 g/kg IV.
  c. Have the patient lie flat in bed.
  d. Suction the patient to see if improving his airway will help his ICP.

Answer to Question 1

C
Hypovolemia results in a loss of circulating fluid volume. A decrease in circulating volume leads to a decrease in venous return, which results in a decrease in end-diastolic volume or preload.

Answer to Question 2

B
Mannitol is an osmotic diuretic and will pull swelling out of edematous brain tissue, thereby decreasing intracranial pressure (ICP). Having the patient lie flat in bed will impair venous drainage from the head and worsen ICP. Suctioning will cause increased intrathoracic pressure, which will also worsen the already elevated ICP.
